摘要
20世纪是荒漠化概念形成与发展的主要时期。荒漠化研究涉及到全球各个地区,研究时段由现代推前到整个人类历史时期,研究内容涉及到自然与社会的许多方面,由于研究基础薄弱,研究缺乏系统性,定量研究不够,一些荒漠化基本理论问题还没有解决。
Desertification is one of the most important problems in the world. The study on desertification has become one of the most important topics in recent years because of its immense harm. This paper simply looks back the development process of the study on desertification, analyses and discusses the points in the debate of some basic problems of desertification, such as desertification definition,distribution space and time, cause, process, indicators and development trend of desertification. This paper gives the main topics of desertification which we must study lately. All in all, there were many problems in the study on desertification in the past, but those problems can be solved through the systematic and quantitative study on desertification.
